The combination of interference and circular SAR (CSAR) can reduce the influence of high sidelobes in the vertical direction of CSAR while retaining the merits of CSAR, such as subwavelength resolution and 3D imaging capability. However, C-band repeated pass interference is difficult due to short wavelength and decorrelation. This paper introduces interferometric processing of CSAR using fully polarimetric C-band circular data which is acquired over a test site in Zhuhai, China. The phase of 2D CSAR images obtained at two different platform height in the same subaperture is different. And the interferogram is acquired based on the phase difference. The experiment verifies the feasibility of repeated pass interference model for CSAR at C-band.
